TO ALLPERSONS TO WHOM THESE PRESENTS MAY COME:r

Be it known that I, AI B. SHAW, of Holderness, in the county of Grafton, and'State of New Hampshire, have invented an improved Folding-Umbrella, and do hereby-declare the same to be fully described in the following specification, andrepresented inthe accompanying drawings,iof which- Figure 1 denotes a` longitudinal section of it.` i

Figure 2 is an under side view of the connection of the two rods of each compound rib.

In the drawings, A denotesthe stai or stick as composed of two portions, at, provided with a slide-tube, andhinged together, sothat onemay be turned down alongside of the other. B B are the ribs, and C the cover, ot' cloth, applied to them. D is the runner, and'E E, Stb., its series ot' spreaders or rods, hinged to it and extended from it to the ribs. Each rib B, I construct of two steel rods, c d, one of which, (viz, 0,) at its lower end, is attachedA to a slider, e, through which the other is passed. The upper end of such rod c is hinged to a collar,f, fixed on the staff. The upper end of the lower rod d is iixedto another slider, g, which encom-` passes and slides freely on the rod, and lis jointed to o ne of .the spreader-rods E. Furthermore, on the staff is another runner, F, carrying or having hinged to it another series of'spreaders or rods, Gr G, each of which is hinged tov one of the sliders g. A cord, L, fastened to the auxiliary runner F, serves to enable a person to depress the said runner onAthe, staff preparatory to closing the umbrella. The spring-catch for holding the main runner in its highest position is shown at H as formed with a bent arm or stop, z', which serves to arrest the runner after it may have passed the shoulder of the catch, and thus prevents undue strain on'the ribs.' The ferrule or part I of the stall' which projects beyond the cover, I apply to the portion a of the 'staii by screwing one to the other, as shown at fr, and by means of a helical spring, m, one end of which is attachedto the head n oi" the part a. The other. end of such spring is aixed to a button or slider, o, arranged within the ferrule,

which is tubular, and provided with a shoulderfp, for the slider to bring u p against when the ferrule is drawn up on the spring. The ferrule `so connected to theA statl' may be nnscrcwed therefrom and turned down against the cover so as to shorten the umbrella, the helical spring serving 'to keep the ferrule in connection with the sta'. The purpose of the auxiliary runner F and its series of spreaders is to prevent the lower part b of each rib from sliding upward when the umbrella is open, in which case the 'auxiliary runner will be up against the hinge collar of the ribs.

In order to prepare t irst be pulled downwardon the stati. s o as to he umbrella for being closed and folded or shortened, 'theiauxiliaryv runner Fshould bring each of the spreaders of suchrunner into an acute angle with the upper parta of the stati'. Next, the main vrunner I) should also be depressed on the steif, and the slide-tube t of the hinge-joint ofthe staff should 'also bc drawn downso as to uncover the joint. Now, it" the umbrella be closed in the ordinary way, lay hold of the handle of the staff 'with one hand, and grasp the cover of the umbrella with the other hand, 'and force the cover upward with respect to the-upper rod so'as to accordingly shorten the umbrella. After this, theupper and lower portions of the steif, that is, the ferrule and handle parts, may be turned or folded clown upon the cover. The umbrella will thereby be materially'reduccd in its length.

I claim the combination of the auxiliary runner F andV its series of spreaders G with the stati', the main runner D, and itsseriesfof spreadersiE, and Aeachoi the ribs, formed in two parts, c d, and applied together, substantially as described. i I

I also claim the connection o to such ferrule and stat?, substantially as set forth.

I also claim the connection ot' the ferrule to the lstaii by them, substantially as specified.

f the ferrule to the stati` by means of the spring, arranged within and applied Vmeans -ot` the screws and the spring applied to I B. SHA-w.
